Is it being restored as hobby or to make money. If the latter, one in rather better condition has an expected auction price of £3,400 – 3,800. So worth doing if it can be restored, time and parts, for that sort of money.
You obviously have not restored a motorcycle in recent years. That sort of money would be lucky to cover the cost of the required parts (and there will be many inside the engine and gearbox and magneto etc needed), paint work and chrome and zinc plating to bring it to fully restored standard. Then the tank may well be rusted out inside and need major expensive surgery. And on and on. You would get nowt for your labour doing it all. And there would be an easy 500 hours in that restoration, possibly as many as 1,000 if it is bad inside. There is no money to be made restoring old motorbikes anymore. Costs have skyrocketed. But demand for bikes of this era has not. Japanese classics of the 1970s and 80s seem to be flavour of the month right now with $25,000 (12,500 Quid) Kawasaki 900s and Honda 4s etc being common.
Personally though, I would not restore that bike. Just freshen it up mechanically and ride it as is. Unrestored survivors — the legendary "barn find" — are increasingly rare these days and worth good money, in some cases more than a fully restored model.
Probably worth a few quid as is, being a rare model and being so unusually complete and unmolested. Plenty of bikes have been restored from far less and far worse beginnings.
+1 on contact the Sunbeam owners club or your local vintage or classic bike club for an idea on its value. Dealers would not have a clue on this kind of stuff. If you put it up for auction and publicise it well it could draw a lot of interest.
And +1 on don't do anything to get it ready for auction. 'As found" is what people want and will pay for. Hosed down and scrubbed up it just looks like someone's unfinished project and has lost its originality.
